Warangal Air Funnel Zones
AAI
Overview
The Warangal airport height restriction zone covers land around Mamnoor Airport (ICAO: VOWA), currently under redevelopment with a sanctioned ₹850 crore project for a 2,500-metre runway and new terminal. This layer, based on AAI Colour Coded Zoning Maps data, shows the Obstacle Limitation Surfaces (OLS) that cap building heights across a 20 km radius from the Aerodrome Reference Point. Anyone buying land near Mamnoor for construction must check these zones before signing. The 1acre premium layer maps these restrictions against actual survey numbers so you know exactly what you are walking into.

At 7 km from Mamnoor, buildings only need AAI approval above 140 metres, which is more permissive than metros like Amritsar. But that figure applies to the peripheral ring only. Inside the funnel path, the ceiling is far lower and non-negotiable. Violations are dealt with under the Aircraft (Demolition of Obstructions) Rules, 1994, which means compulsory demolition, not just a fine.
Apply for height clearance through NOCAS (nocas2.aai.aero) before you approach the local body for any building permit. If the CCZM permissible elevation covers your planned height, local authorities can clear you without a direct AAI application. If it does not, you must go through AAI first. Starting construction without clearance is not a paperwork oversight. It is a statutory violation.

The most misunderstood corridor is the 1–5 km ring around Mamnoor village itself. Sellers market it as the prime airport-proximity zone. From an investment standpoint the proximity is real, but what they do not say is that plots in this ring sit squarely inside the inner horizontal surface or funnel zone. You can own the land. You cannot build freely on it. For warehousing, low-rise logistics, or agricultural use, this zone works. For residential plots above 3 or 4 floors, it does not, and no local builder can override AAI.
The Kakatiya Mega Textile Park proposal and NIT Warangal's presence give the wider Warangal land market more than one growth lever beyond the airport. Land with road access to NH-563 or the Warangal Outer Ring Road, sitting outside the inner restriction zones, has the cleanest risk profile for buyers who want to build.
Frequently Asked Questions
Do I need an AAI NOC to build on land within the Warangal airport height restriction zone?
Yes. Under the Height Restrictions for Safeguarding of Aircraft Operations Rules, 2015, all structures within 20 km of Mamnoor's Aerodrome Reference Point require a No Objection Certificate from AAI via the NOCAS portal before construction can begin.
What is the air funnel zone and what does it mean for my plot near Warangal airport?
The air funnel zone runs along the runway axis. Building height is capped at 2% of your distance from the runway end. At 1 km distance, the maximum height is 20 metres. It is the strictest zone in the entire OLS framework.
At 7 km from Mamnoor airport, how tall can I build without AAI approval?
At 7 km, in Warangal only buildings above 140 metres require direct AAI approval. This is more permissive than most cities. However, the CCZM for your specific grid coordinates is the definitive number, not a general rule.
Which villages near Mamnoor airport are under active land acquisition?
Nakkalapally, Gadipally, and Gunturpally are under acquisition orders issued via G.O. M.S. No. 36 (2023). Farmers in Gunturpally protested compensation of ₹1.20 crore per acre against a claimed market rate of ₹4 crore per acre.
Will Warangal Mamnoor airport development increase land prices nearby?
It already has. Agricultural land near Mamnoor doubled from roughly ₹1 crore to ₹2 crore per acre after the redevelopment announcement. The full ₹850 crore project is approved but land handover to AAI is still in progress. Price appreciation depends on construction timeline.
What happens if I build without AAI clearance near Warangal airport?
Violations are handled under the Aircraft (Demolition of Obstructions Caused by Buildings and Trees) Rules, 1994. The authority can require compulsory demolition of the non-compliant floors or the entire structure. There is no fine-only option.
How do I check the exact permitted building height for my plot near Mamnoor?
Check the Colour Coded Zoning Map for Warangal Airport on the AAI NOCAS portal (nocas2.aai.aero). Input your plot's GPS coordinates. If your planned height stays within the CCZM permissible elevation, the local body can clear you. If it exceeds it, apply directly to AAI.
Can I use land near Mamnoor airport for warehousing or low-rise industrial use?
Low-rise structures that stay within the OLS-permitted height for their specific zone are viable. Single-storey and two-storey logistics or agricultural facilities typically fall below funnel zone thresholds. Confirm the exact limit for your survey number on NOCAS before committing.
